Description

SGSN间切换的实现方法 Implementation inter SGSN handover

技术领域 FIELD

本发明涉及网络通信技术领域,尤其涉及一种SGSN间切换的实现方法。 The present invention relates to network communication technology, and particularly relates to a method to realize inter-SGSN handover. 背景技术 Background technique

SGSN ( Serving GPRS (General Packet Radio Service,通用分组无线业务)Support Node,服务GPRS支持节点)是GPRS/UMTS (Universal Mobile Telecommunications System,通用移动通讯系统)分l且域核心网络的主要设备,完成分组lt据包的路由与转发、加密与鉴权、会话管理、移动性管理、 逻辑链路管理、话单产生和输出等功能。 SGSN (Serving GPRS (General Packet Radio Service, General Packet Radio Service) Support Node, a Serving GPRS Support Node) is a GPRS / UMTS (Universal Mobile Telecommunications System, Universal Mobile Telecommunications System) points l and a main device domain core network, the completion packet routing and forwarding lt packets, encryption and authentication, session management, mobility management, logical link management, and then to produce a single output function. 它在移动通信网络中的位置如图l所示:SGSN在PS (Packet Service,分组业务)域中的位置和CS (英文,中X )域的MSC (Mobile Switch Center,移动交换中心)/VLR (英文,中文) 类似,其核心功能是通过MM ( Mobility Management ,移动性管理)、SM (Session Management,会话管理)、GTP (隧道管理)等实现业务数据在MS ( Mobile Subscriber ,移动用户)与GGSN ( Gateway GPRS Support Node,网关GPRS支持节点)之间的路由及转发功能。 Its location in the mobile communication network as shown in Figure l: SGSN position PS (Packet Service, packet service) domain and a CS (in English, the X) domain MSC (Mobile Switch Center, Mobile Switching Center) / VLR (English, Chinese) Similarly, its core function is through the MM (mobility management, mobility management), SM (session management, session management), GTP (tunnel management), etc. to achieve business data in the MS (mobile Subscriber, mobile users) and GGSN (gateway GPRS support node, gateway GPRS support node) routing and forwarding between.

用户必须进行附着和PDP激活才能进行数据传输。 The user must be attached to the PDP activation and data transmission. 在附着流程中,SGSN 从HLR ( Home Location Register,用户归属寄存器)取得用户的签约数据, 通过签约数据判断是否允许用户接入。 In the attachment process, SGSN HLR (Home Location Register, the user home register) to obtain the subscription data from the subscription by determining whether to allow the user access to the data. 签约数据中还包括PDP (Packet Data PlDtocol,分组数据协议)上下文的签约信息。 Subscription data further comprises subscription information PDP (Packet Data PlDtocol, Packet Data Protocol) context. 在PDP激活流程中,SGSN会根据用户请求的数据和用户在HLR中的签约数据进行比较,判断是否允许 In the PDP activation procedure, the SGSN will compare the data requested by the user and the user subscription data in the HLR, determines whether to permit

PDP上下文建立。 PDP context establishment. 签约PDP上下文中还包括签约QoS (Quality of Service,月良务质量)信息。 PDP context subscription contract also includes QoS (Quality of Service, Quality of Service good month) information.

QoS是第三代通信系统为用户提供更宽的带宽、更稳定的个性化服务的保证。 QoS is a third generation communication system to provide users with a wider bandwidth, to ensure a more stable personalized service.

众所周知,阿络服务是按照端到端来实现的。 As we all know, A network service is in accordance with the end to achieve. 只有网络的各个实体都提供了相应的QoS保证,用户才能得到希望的QoS。 Only the various entities of the network provides corresponding QoS guarantees, users can obtain the desired QoS.

作为分组域核心网设备,在PDP上下文的激活流程中,SGSN根据自身的能力,对MS (移动台)请求的QoS、用户签约的QoS进行协商,得到协商的QoS,并且把协商的QoS通知给GGSN、 RNC、 BSS及UE等相关实体,使各网络实体都保存统一的QoS,并实现该QoS。 As the packet domain core network device, the PDP context activation process, the SGSN according to their ability to MS (mobile station) requests a QoS, a user subscribed QoS negotiation, to obtain QoS Negotiated, and the negotiated QoS notifies GGSN, RNC, BSS UE and other related entities, so that all network entities are kept consistent QoS, and to achieve the QoS. 这样,用户才能在最终进行数据传输中得到应有的服务。 In this way, users can get the necessary services in the final data transmission.

随着通信技术的不断发展,3GPP协议中的QoS属性也经历了多个协议版本的演化,从QoSR97/98 (97/98版本的服务质量)、QoSR99 (99版本的服务质量) 一直发展到现在的QoSR5 (2005版本的服务质量)。 With the continuous development of communication technology, QoS attributes 3GPP protocol has gone through multiple protocol versions of evolution, from QoSR97 / 98 (97/98 version of the Quality of Service), QoSR99 (99 version of the quality of service) has been developed to the QoSR5 (2005 version of the quality of service). 在这个发展过程中,QoS属性也发生了变化。 In this development process, QoS property has changed. 比如,QoSR97/98与QoSR99属性包含完全不同的参数。 For example, QoSR97 / 98 and QoSR99 attribute contains different parameters. 由于在实际应用中一套GPRS/UMTS分组域网络的全系统设备中, 各个网元所支持的QoS版本均有可能不同,为了保证UMTS设备与现网GPRS 设备之间互连互通的可靠性,必须做到QoSR97/98设备和QoSR99设备的兼容,。 Since in the practical application of a GPRS / UMTS system-wide packet domain network devices in each network element supports different QoS versions are possible, in order to ensure the reliability of the device between the UMTS and the GPRS device existing network interconnection, It must be accommodating QoSR97 / 98 device and QoSR99 equipment.

因此考虑到兼容性,协议3GPP TS 23.107规定了QoSR97/98参数和Q'oSR99参数之间的映射规则。 Thus considering the compatibility protocol 3GPP TS 23.107 specifies the mapping rules QoSR97 / 98 Q'oSR99 parameters and parameter.

协议3GPP TS 23.107规定从QoSR97/98属性到QoSR99属牲的映射应用于:PDP上下文从GPRS R97/98 SGSN (即支持97/诉版本服务质量的SGSN ) 切换到UMTS或GPRS R99 SGSN (即支持99版本服务质量的SGSN)。 3GPP TS 23.107 protocol from a predetermined QoSR97 / 98 QoSR99 mapping attributes to be applied to the genus sacrifice: PDP context from the GPRS R97 / 98 SGSN (i.e., support 97 / v quality version of the service SGSN) to a UMTS or GPRS R99 SGSN (i.e., a 99 version of the quality of service SGSN). 同时, 协议3GPP TS 23.060规定,PDP上下文从GPRS R97/98 SGSN切换到UMTS或 Meanwhile, a predetermined protocol 3GPP TS 23.060, the PDP context switch from GPRS R97 / 98 SGSN to UMTS or

GPRS R99 SGSN时,新侧SGSN负责将QoSR97/98参数映射为QoSR99参数。 GPRS R99 SGSN, the new SGSN is responsible for mapping side QoSR97 / 98 QoSR99 parameter parameter.

协议3GPP TS 23.107规定从QoSR99属性到QoSR97/98属性的映射应用子:PDP上下丈从UMTS/GPRS R99 SGSN切换到GPRS R97/98 SGSN 。 3GPP TS 23.107 protocol from a predetermined property to QoSR99 QoSR97 / 98 sub-attribute mapping applies: PDP feet vertical handover from UMTS / GPRS R99 SGSN to the GPRS R97 / 98 SGSN. 同时, 协议3GPP TS 23.060规定,PDP上下文从UMTS或GPRS R99 SGSN切换到GPRS R97/98 SGSN时,旧侧SGSN负责将QoSR99参数映射为QoSR97/98参数。 At the same time, a predetermined protocol 3GPP TS 23.060, or the PDP context switch from the UMTS to the GPRS R99 SGSN GPRS R97 / 98 SGSN, the old SGSN is responsible for mapping side QoSR99 parameters QoSR97 / 98 parameters.

用户在移动的过程中,可能在不同的BSS ( GSM基站子系统)/RNC (Radio Network Control,无线网络控制)之间切换,如杲新旧BSS/RNC属于不同的SGSN,则需要通过SGSN间的位置管理流程将用户MM上下文和PDP 上下文从旧侧SGSN迁移到新侧SGSN ,这个过程称之为SGSN间的切换流程。 During movement of the user, may switch between different BSS (GSM Base Station Subsystem) / RNC (Radio Network Control, the radio network control), such as old and new Gao BSS / RNC belong to different SGSN, the SGSN between the need user location management procedures MM context and PDP contexts from the old migration side SGSN to the new SGSN side, a process known as handoff process between the SGSN.

现有技术方案的SGSN间的切换流程如图2所示。 SGSN handover procedure between the prior art embodiment shown in Figure 2.

在SGSN间的切换过程中,旧倒SGSN会通过SGSN Context Response (SGSN上下文响应)消息将PDP上下文在旧侧SGSN请求的QoS、用户签约的QoS和使用的QoS,发送给新侧SGSN。 In the switching process between the SGSN, the old SGSN will be inverted (SGSN Context Response) by the SGSN Context Response message the PDP context in the old QoS side SGSN requests, QoS user subscribed QoS and used, the transmission side to the new SGSN. 新側SGSN根据这些QoS,结合自身的能力,协商出新的QoS,并将这个新的QoS通过Update PDP Context Request (更新PDP上下文请求)消息通知给GGSN。 Based on these QoS New SGSN side, with its own capabilities, the new negotiated QoS, and new QoS by this Update PDP Context Request (Update PDP Context Request) message notifies the GGSN. 然后新侧SGSN向HLR发送Update GPRS Location (更新GPRS位置)消息通知HLR进行SGSN位置更新, HLR接到通知后会取消旧倒SGSN中保存的用户的签约数据,并将用户的签约数据通过Insert Subscriber Data (插入用户签约数据)消息发送给新侧SGSN。 Then the new SGSN sends to the side HLR Update GPRS Location (Update GPRS Location) message SGSN informs the HLR for location updating, the HLR after receiving the notice to cancel the old inverted saved subscription data in the SGSN, and subscription data through Insert Subscriber the data (user subscription data insertion) message to the new side SGSN.

但是现网设备中,有些设备并不会完全执行协议的规定。 However, existing network equipment, some equipment does not fully implement the provisions of the agreement. 如杲HLR和/或UE中的QoSR99属性和QoSR97/98属性不遵守QoSR97/98与QoSR99之间的映射规則,当用户因为位置移动,在支持不同协议版本的SGSN之间反复切换 As Gao HLR and / or properties of the UE and QoSR99 QoSR97 / 98 non-compliance with the attribute mapping rules QoSR97 / 98 and QoSR99, because when the user moves the position of repeatedly switching between different protocol versions supported SGSN

时,由于SGSN基于用户签约中的QoSR97/98属性协商新的QoS,可能会引起实际使用的QoS属性与签约的QoS属性不符;而当实际使用的QoS属性大于签 When, due to the new SGSN QoS negotiation based on the user subscription QoSR97 / 98 properties, may cause the actual QoS attributes does not match the sign of QoS attributes; QoS attributes when actually used is larger than sign

约的QoS属性时,给用户提供的带宽超过用户的需求,造成资源浪费,引起通营商的不满;当实际使用的QoS属性小于签约的QoS属性时,给用户提供的带宽不能满足用户的需求,会引起用户的不满。 About QoS attributes, the bandwidth in excess of the needs of users to users, resulting in waste of resources caused through business dissatisfaction; when QoS attributes actually used less than QoS attributes contract, to provide the bandwidth can not meet the needs of users It can cause user dissatisfaction.

下面举例说明采用现有技术方案导致实际使用的QoS属性大于签约的QoS 属性的情况。 The following example illustrates use of the prior art solutions lead to QoS attributes is greater than the actual signing of the QoS attributes.

假设,用户签约的QoSR99属性中,上下行Maximum bitrate (最大彼特率)均为64kbps,但QoSR97/98属性中的Peak throughput class (中文)为9, 不满足协议规定QoSR99属性到QoSR97/98属性的映射规则;MS支持0oSR99; SGSN1支持UMTS或GPRS R99, SGSN2只支持GPRS R97/98;在输SN协商QoS时,不考虑其自身的能力,只根据用户签约QoS和请求的QoS 共同协商使用的QoS。 Suppose, the user subscribed QoSR99 properties, uplink and downlink Maximum bitrate (Petter maximum rate) are 64kbps, but QoSR97 / 98 properties Peak throughput class (Chinese) 9, the attribute does not satisfy the agreement QoSR99 QoSR97 / 98 Properties mapping rules; MS support 0oSR99; SGSN1 support UMTS or GPRS R99, SGSN2 only supports GPRS R97 / 98; at input SN negotiated QoS, without considering its capabilities, only according to the user subscription QoS and requested QoS consultation used QoS. MS使用QoSR99属性接入SGSNl, MS请求的QoS属性和用户签约的QoS属性相同,SGSN1最终协商使用的QoS属性也与用户签约的QoS属性相同。 MS uses the access attribute QoSR99 SGSNl, the same QoS attributes, and user subscription MS requests QoS attributes, the same final negotiated QoS attributes using SGSN1 also signed with the user's QoS attributes.

当MS因为位置移动,需要将PDP上下文切换到SGSN2时,SGSN1通过SGSN Context Response消息,将PDP上下文发送给SGSN2。 When the MS because the position, the PDP context needs to be switched to the SGSN2, SGSN1 by the SGSN Context Response message the PDP context sent to SGSN2. 根据协议的规定,SGSNl将MS请求QoS、签约QoS和最终协商QoS属性中的QoSR97/98部分传送给SGSN2。 Under the protocol, SGSNl the MS requests QoS, subscription QoSR97 / 98 and the final part of the transport QoS negotiation of QoS attributes to SGSN2. 这样,SGSN2接收到的请求QoS和签约QoS中的Peak t阶ou缺put class仍为9,通过这些参数协商的QoS中的Peak throughput class也为9, SGSN2会使用这个协商QoS去更新GGSN。 Thus, SGSN2 receives the subscription request and QoS in QoS order Peak t put class still missing ou 9, negotiated QoS parameter of these Peak throughput class also 9, SGSN2 uses this to update the negotiated QoS GGSN.

当MS因为位置移动,又将PDP上下文从SGSN2迁回SGSN1时,SGSN2将PDP上下文发送给SGSN1。 When the MS position because, in turn move back a PDP context from SGSN1 SGSN2, SGSN2 sends the PDP context to SGSN1. 根据协议的规定,SGSN2将MS请求QoS、签约QoS和最终协商QoS属性(均为QoSR97/98 )传送给SGSN1。 Under the protocol, SGSN2 requests the MS QoS, QoS and signing the final negotiated QoS attributes (both QoSR97 / 98) is transmitted to SGSN1. SGSN1确认UE 的网络能力支持R99,需要将QoSR97/98属性转换成QoSR99属性,根据 SGSN1 confirm the network support capabilities of the UE R99, you need to convert QoSR97 / 98 QoSR99 properties to properties based on

QoSR97/98属性到QoSR99属性的映射规则,这时签约QoS和请求QoS中的Maximum bitrate变成了2048kbps,通过这些参数协商出的QoS中的Maximum QoSR97 / 98 QoSR99 attributes to attribute mapping rules, when the subscription request and QoS in QoS Maximum bitrate becomes 2048kbps, these parameters negotiated QoS of the Maximum

bitrate也变成了2048kbps ,然后SGSN1会使用这个异常的协商QoS去更斩GGSN。 bitrate has become a 2048kbps, then SGSN1 will use this unusual negotiated QoS to cut more GGSN. 这样,实际^f吏用的QoS属性远远大于签约的QoS属性u因此会造成資源浪费,引起运营商的极大不满。 Thus, the actual f ^ QoS attributes officials with far greater than the QoS attributes signing of u and therefore a waste of resources, caused great discontent operators.

发明内容 SUMMARY

鉴于上迷现有技术所存在的问题,本发明的目的是提供一种SGSN间切换的实现方法,在SGSN之间切换过程中,基于用户签约QoSR99属性协商新的QoS,能够保证实际使用的QoS属性符合用户签约的QoS属性,从而提高运营商和用户的满意度。 In view of the above-prior art problems, an object of the present invention is to provide a method of achieving inter-SGSN handover, the handover process between the SGSN, the new negotiated QoS attributes QoSR99 based on user subscription, to ensure QoS actually used QoS attributes consistent with attributes of the user contract, thereby increasing the satisfaction of operators and users.

本发明提供的方法包括两种具体实现方案, 一种是当旧側SGSN为UMTS/GPRS R99 SGSN,且新側SGSN为GPRS R97/98 SGSN时,另外一种是当新侧SGSN为UMTS/GPRS R99 SGSN ,且旧側SGSN为GPRS R97/98 SGSN,且MS支持QoSR99时,SGSN间切换的实现方案。 The method of the present invention comprises two specific implementations, one is when the old SGSN side of UMTS / GPRS R99 SGSN, and the SGSN side of the new GPRS R97 / 98 SGSN, when another new SGSN side of UMTS / GPRS R99 SGSN, and the SGSN side of the old GPRS R97 / 98 SGSN, and the MS support QoSR99, the implementation of the inter SGSN handover.

本发明提供的技术方案一的流程与现有SGSN间的切换流程基本相同, 不同之处在于:当旧側SGSN收到新側SGSN的SGSN上下文请求后,将MS请求QoS和/或用户签约QoS按照QoSR99属性到QoSR97/98属性映射规则转换出相应的QoSR97/98属性,并发送给新側SGSN。 Aspect of the present invention provides a process and the handover procedure is substantially the same among existing SGSN, except that: when the new SGSN receives the lateral side of the old SGSN in an SGSN Context Request, the MS requests QoS and / or user QoS subscription QoSR99 property according to QoSR97 / 98 conversion the attribute mapping rules corresponding QoSR97 / 98 properties, side sends the new SGSN.

优选方案是:当旧側SGSN收到新侧SGSN的SGSN上下文请求后,首先判断PDP上下文中的MS请求QoS和用户签约QoS是否满足QoSR99属性到QoSR97/98属性映射规则,如果不满足映射规则,则将MS请求QoS和/或用户奮约QoS按照QoSR99属性到QoSR97/98属性映射规则转换出相应的QoSR97/98属性,并发送给新側SGSN。 Preferred is: when the new SGSN receives the side of the side of the old SGSN SGSN Context Request, first determines whether the MS requests a PDP context QoS and user subscription meets QoS attributes to QoSR99 QoSR97 / 98 attribute mapping rules, and if not mapping rule, then the MS requests QoS and / or user QoS excited to about QoSR97 / 98 QoSR99 attribute mapping rule conversion according to the corresponding attribute QoSR97 / 98 properties, side sends the new SGSN.

下面将结合附图对本发明提供的技术方案一进行详细的说明。 Following with reference to the aspect of the present invention provides a detailed description.

本发明提供的技术方案一的具体实现方式参照如图2所示的SGSN间切换流程,包括以下步骤: Inter SGSN aspect the present invention provides a specific implementation shown in Figure 2 with reference to handover procedures, comprising the steps of:

步骤201:当用户因为位置移动,需要在支持不同协议版本的SGSN之间切换时,MS向新侧SGSN发起路由区更新请求。 Step 201: When the user because the position, switch between different protocol versions supported SGSN, MS initiates a routing area update request to the new side SGSN.

MS可以通过向新側SGSN发送Routeing Area Update Request (路由区更新请求)消息发起路由区更新请求。 MS may Routeing Area Update Request (Routing Area Update Request) by transmitting a message to the new SGSN side initiates a routing area update request.

Context Request (SGSN上下文请求)消息请求该MS的PDP上下文。 Context Request (SGSN Context Request) message that the MS requests a PDP context.

步骤203:旧侧SGSN收到SGSN Context Request消息后,判断该MS的 Step 203: SGSN side Old SGSN Context Request message is received, the MS determines

P0P上下文中的用户签约QoS和/或MS请求QoS信息中的QoSR99属性和 P0P user subscription context QoS and / or MS requests QoS QoSR99 attribute information and

QoS砂7/R98属性之间是否满足协议3GPP TS 23.107规定的QoSR99属性到 QoSR99 attribute satisfies a predetermined QoS between 3GPP TS 23.107 protocol Sand 7 / R98 attributes to

QoSR97/98属性的映射规则(即下面表l中的映射规则); Mapping rules QoSR97 / 98 attributes (i.e., below Table l in the mapping rules);

如果用户签约QoS和请求QoS信息均满足协议失见定的映射关系,则旧侧 If the user subscription request and QoS protocols to meet QoS information is given out to see mappings old side

SGSN直接将该MS的PDP上下文中的用户签约QoS、 MS请求QoS和实际使用 The SGSN directly to the MS in the PDP context QoS user subscription, MS requesting QoS and actual

QoS中的QoSR97/R98属性通过SGSN Context Response消息发送给新侧 The QoS QoSR97 / R98 attribute to a new SGSN Context Response message by side

SGSN; SGSN;

如杲用户签约QoS和/或请求QoS信息不满足协议规定的映射关系,则旧ll'SGSN按照表1的映射规则修改用户签约的QoS和/或请求QoS信息的^SR97/R98属性,也就是将用户签约QoS和/或请求QoS的QoSR99属性按照协议规定的映射规则转换出相应的QoSR97/98属性,然后将转换出的QoSR97/98属性以及PDP上下文信息中不需要转换的QoS信息通过SGSN Context Response消息发送给新倒SGSN。 Gao QoS as the user subscription and / or the request does not satisfy a predetermined relationship mapping QoS information protocol, the modified user subscription ll'SGSN old mapping rule in accordance with Table 1 QoS and / or requested QoS information ^ SR97 / R98 attributes, i.e. QoS user subscription and / or conversion requested QoS attributes according to the mapping rule QoSR99 predetermined protocol the corresponding QoSR97 / 98 properties, and then converted by the QoSR97 / 98 QoS information of the PDP context and attribute information need not converted by the SGSN context Response messages to pour new SGSN.

步骤204:新侧SGSN收到SGSNContextResponse消息后向旧侧SGSN发送SGSN Context Acknowledge (SGSN上下文应答)消息,表示收到该MS的PDP 上下文信息; Step 204: after receiving the new SGSN side SGSNContextResponse message SGSN Context Acknowledge (SGSN Context Response) message to the old SGSN side, to acknowledge the receipt of the PDP context information of the MS;

然后,新側SGSN根椐收到的用户签约QoSR97/98属性,或者根据收到的用户签约QoSR97/98属性和请求QoSR97/98属性,或者根据收到的用户签约QoSR97/98属性和实际使用Qo&R97/98属性,并结合自身能力协商(即确定) 出新的QoS. Then, the user-side new SGSN noted in the received subscription QoSR97 / 98 properties, or subscription QoSR97 / 98 according to a user request and attributes received QoSR97 / 98 properties, or subscription QoSR97 / 98 Qo and the actual use properties according to the received user & R97 / 98 properties, combined with their capability negotiation (i.e., determining) the new QoS.

步骤205:新側SGSN将协商出的新QoS通过Update PDP Context Request消息发送给GGSN,通知GGSN更新QoS。 Step 205: The new side SGSN transmits the negotiated QoS to the GGSN via a new Update PDP Context Request message, the GGSN updates the notification QoS.

步骤206: GGSN收到新QoS信息后向新側SGSN发送Update PDP Context Response (更新PDP上下文响应)消息。 Step 206: The GGSN receives the new QoS information transmitted Update PDP Context Response to the new side SGSN (Update PDP Context Response) message.

步骤207:新側SGSN通过向HLlH送Update GPRS Location消息通知HLR 进^tSGSN位置更新。 Step 207: The new SGSN by sending Update GPRS side HLlH Location message to the HLR notifies ^ tSGSN into a location update.

步骤208: HLR收到SGSN位置更新消息后,通过向旧侧SGSN发送Cancel Loc必加(取消位置)消息通知旧側SGSN删除其保存的该MS的用户签约数据。 Step 208: HLR SGSN receives the location update message, a notification message to delete the old SGSN side of the MS user's subscription data save by sending Cancel Loc side will be added to the old SGSN (cancellation position).

步骤209:旧倒SGSN删除其保存的该MS的用户签约数据后向HLR发送Cancel Location Ack (取消位置应答)消息。 Step 209: The old SGSN deletes the inverted MS save the user data sent after signing Cancel Location Ack to the HLR (a Cancel Location Acknowledgment) message.

步骤210: HLR接到旧倒SGSN的Cancel Location Ack消息后,将该MS的用户签约数据通过Insert Subscriber Data消息发送给新側SGSN。 Step 210: After receiving Cancel Location Ack message HLR down the old SGSN and the MS user's subscription data to the new SGSN by side Insert Subscriber Data message.

步骤211:新側SGSN收到该MS的用户签约数据后进行保存并向HLR发送Insert Subscriber Data Ack (插入用户签约数据应答)消息。 Step 211: The new SGSN receives the side of the user of the MS to be saved after the subscription data sent by the HLR Insert Subscriber Data Ack (the user subscription data insertion acknowledgment) message.

步骤212: HLR收到新側SGSN的插入用户签约数据应答消息后向新侧SGSN发送Update GPRS Location Ack (更新GPRS位置应答)消息。 Step 212: HLR-side new SGSN receives user subscription data insertion acknowledgment message sending Update GPRS Location Ack to the new side SGSN (Update GPRS Location Acknowledge) message.

步骤213:新側SGSN收到HLR的Update GPRS Location Ack消息后,将其协商出的QoS属性通过Routeing Area Update Acc印t (路由区更新接受)消息发送给MS。 Step 213: After the new SGSN receives an HLR-side Update GPRS Location Ack message to the negotiated QoS attributes (routing area update accept) by Routeing Area Update Acc t printed message to the MS.

本发明提供的技术方案二的流程与现有SGSN间的切换流程基础上增加了一个QoS修改流程,即新倒SGSN向MS发送了Routeing Area Update Acc印t 消息后,根据HLR发送的签约数据中的QoSR99属性重新协商QoS,并将重新协商的QoS通知给GGSN和MS。 The present invention provides a technical solution based on the increase in the switching process between the two processes and the conventional QoS modification procedure a SGSN that the new SGSN sends down a Routeing Area Update Acc t printed message to the MS, the HLR subscription data according to the transmission the QoSR99 property renegotiate QoS, and QoS renegotiation of the notification to the GGSN and the MS.

下面将结合附图对本发明提供的技术方案二进行详细的说明。 Following with reference to the aspect of the present invention provides two be described in detail.

本发明提供的技术方案二的具体实现方式如图3所示,包括以下步骤: 步骤301:当用户因为位置移动,需要在支持不同协议版本的SGSN之间 Aspect of the present invention provides two particular implementation shown in Figure 3, comprising the following steps: Step 301: when the user because the position of the mobile, the need to support different protocol versions between the SGSN

切换时,MS向新侧SGSN发送Routeing Area Update R叫uest消息发起路由区更 Handover, MS transmitting side to the new SGSN Routeing Area Update R initiates a routing area message called uest more

新请求。 The new request.

步骤302:新侧SGSN接到MS的路由区更新请求后向旧侧SGSN发送SGSN Context R叫uest消息请求该MS的PDP上下文。 Step 302: The new side to the SGSN after the MS routing area update request SGSN Context R called uest PDP context request message of the MS side to the old SGSN.

步骤303:旧側SGSN收到SGSN Context Request消息后,将该MS的通过SGSN Context Response消息发送给新側SGSN,该PDP上下文包括:MS在旧側SGSN实际使用的QoS、用户签约QoS和MS请求QoS信息。 Step 303: SGSN side Old SGSN Context Request message is received, the MS is sent to the new SGSN by side SGSN Context Response message, the PDP context includes: MS in the QoS old SGSN side is actually used, and the MS requests QoS subscription user QoS information.

由于旧側SGSN为GPRS R97/98 SGSN,因此向新侧SGSN发送的QoS信息均为QoSR97/98属性。 Since the old SGSN side of GPRS R97 / 98 SGSN, QoS information thus sent to the new SGSN side are QoSR97 / 98 attributes.

步骤3(M:新侧SGSN收到SGSN Context Respcmse消息后向旧侧SGSN发送SGSNContext Acknowledge (SGSN上下文应答)消息,表示收到该MS的PDP 上下文信息。 Step 3 (M: the new SGSN receives the SGSN Context Respcmse side transmits SGSNContext Acknowledge message to the old SGSN side (SGSN Context Response) message to acknowledge the receipt of the PDP context information of the MS.

然后,新侧SGSN根据收到的用户签约QoS和请求QoS和/或实际使用的QbS倌息并结合自身能力,协商出新的QoS。 Then, the new SGSN side and QoS subscription request QoS and / or groom QbS information actually used combined with their ability to negotiate a new user in accordance with the received QoS.

步骤305:新侧SGSN向GGSN发送Update PDP Context R叫uest消息通知SGSN已变更,同时还可以将协商出的新QoS通过该消息发送给GGSN。 Step 305: SGSN sends the new-side Update PDP Context R notification message called uest GGSN to SGSN has changed, but also can be a new negotiated QoS to the GGSN by sending the message.

步骤306: GGSN收到新QoS信息后向新側SGSN发送Update PDP Context Response消息。 Step 306: The GGSN receives the new QoS information transmitted Update PDP Context Response message to the new side SGSN.

步骤307:新侧SGSN通过向HLR发送Update GPRS Location消息通知HLR 进行SGSN位置更新。 Step 307: SGSN sends the new-side Update GPRS Location message SGSN informs the HLR for location update to the HLR.

步骤308: HLR收到SGSN位置更新消息后,通过向旧侧SGSN发送Cancei Location消息通知旧侧SGSN删除其保存的该MS的用户签约数据。 Step 308: HLR receives location update message SGSN notifies the old SGSN side delete the MS user's subscription data save Cancei Location message by sending side to the old SGSN.

步骤309:旧侧SGSN刪除其保存的该MS的用户签约数据后向HLR发送Cancel Location Ack消息。 Step 309: delete the old SGSN side user save the MS transmits Cancel Location Ack message to the HLR after the subscription data.

步骤310: HLR接到旧側SGSN的Cancel Location Ack消息后,将该MS的用户签约数据通过Insert Subscriber Data消息发送给新侧SGSN。 Step 310: After receiving Cancel Location Ack message HLR old SGSN side of the user subscription data to the MS-side new SGSN by Insert Subscriber Data message.

该用户签约数据中包含有QoSR99属性。 The user subscription data includes QoSR99 properties.

步骤311:新侧SGSN收到该MS的用户签约数据后进行保存并向HLR发送Insert Subscriber Data Ack消息。 Step 311: The new SGSN receives the side of the user of the MS to be saved after the subscription data sent by the HLR Insert Subscriber Data Ack message.

步骤312: HLR收到新側SGSN的插入用户签约^f史据应答消息后向新侧SGSN发送Update GPRS Location Ack消息。 Step 312: HLR receives a new SGSN side is inserted into a user subscription ^ f history data after sending a response message to the new side SGSN Update GPRS Location Ack message.

步骤313:新侧SGSN收到HLR的Update GPRS Location Ack消息后向MS 发送Routeing Area Update Accept消息。 Step 313: SGSN receives the new HLR-side after the Update GPRS Location Ack message Routeing Area Update Accept message to the MS.

步骤314: MS^奏到新側SGSN的Routeing Area Update Accept消息后,向新側SdSN发送Routehg Area Update Complete消息。 Step 314: After the MS ^ outs Routeing Area Update Accept message to the new SGSN side, the transmission side to the new SdSN Routehg Area Update Complete message.

根据协议规定,该步骤是个可选步骤。 According to the agreement, which step is an optional step.

步骤315:新侧SGSN根据HLR发送的用户签约数据中的QoSR99属性并结合自身能力重新协商QoS,如果重新协商出的QoS与步骤304中协商出的QoS 不同,则将该重新协商出的QoS通过Update PDP Context R叫uest消息发送给GGSN。 Step 315: The new SGSN side user subscription data sent by the HLR and the attributes of its own ability to QoSR99 renegotiated QoS, different if the re-negotiated QoS and the negotiated step 304 QoS, is the renegotiation of QoS through an Update PDP Context R called uest message to the GGSN.

如果新側SGSN除了根椐用户签约QoS、还需要根据请求QoS和/或实际使用QoS协商新的QoS,那么在协商QoS前,新側SGSN需要将从旧侧SGSN接收到的请求QoS和/或实际使用QoS按照表2的QoSR97/98属性到QoSR99属性的映射规則转换出相应的QoSR99属性,然后再根据用户签约数据中的QoSR99属性,或者根据用户签约数据中的QoSR99属性以及请求QoSR99属性,或者根据用户签约数据中的QoSR99属性和实际使用QoS中的QoSR99属性,并结合自l能力进行QoS的协商, If the new SGSN side except QoS noted in the user subscription, but also need to negotiate the new QoS according to QoS request and / or the actual QoS, QoS negotiated before then, the new SGSN needs side from the reception side the old SGSN to request QoS and / or actual QoS to QoSR99 mapping rule attribute conversion according to table 2 QoSR97 / 98 attributes the corresponding QoSR99 properties, and then subscription QoSR99 attribute data in accordance with a user, or according QoSR99 attribute in the user subscription data and a request QoSR99 properties, or the user subscription data QoSR99 QoS attributes and the actual use of QoSR99 properties and binding capacity of from l to negotiate QoS.

步骤316: GGSN收到该重新协商出的QoS后向新側SGSN发送Update PDP Context Response消息. Step 316: GGSN receives Update PDP Context Response message sent to the new SGSN after the back side of the negotiated QoS.

步骤317:新側SGSN收到GGSN的Update PDP Context Response消息后, 将重新协商后的QoS通过Modify PDP Context Request (修改PDP上下文请求) 消息发送给MS。 Step 317: After the new SGSN receives the GGSN-side Update PDP Context Response message, QoS re-negotiation through the Modify PDP Context Request (PDP context modification request) message to the MS.

步驟318:如果MS接受重新协商后的QoS, MS向新侧SGSN发送Modify PDP Context Accept (修改PDP上下文接受)消息;如果MS不接受更新后的QoS,则将发起PDP去激活流程。 Step 318: If the MS accepts the QoS renegotiation, MS Modify PDP Context Accept transmission side to the new SGSN (Modify PDP Context Accept) message; if the MS does not accept the QoS update, then initiating PDP deactivation process.

因此采用本发明提供的技术方案一和技术方案二,都能够解决HLR和/或MS中的(^)SR99属性和QoSR97/98属性不遵守协议规定的映射规则时可能导致'的实际使用的QoS属性与签约的QoS属性不一致的问题。 Thus the technical solution a and aspect of the present invention provides two, can be solved QoS HLR and / or may cause 'or the MS (^) SR99 properties and QoSR97 / 98 attributes do not comply with the mapping rules of the protocol actually used QoS properties inconsistent with the signing of the problem.

下面详细说明如何采用本发明技术方案一来解决背景技术中的HLR和/或MS中的QoSR99属性和QoSR97/98属性不遵守协议规定的映射规则时导致实际使用的QoS属性大于签约的QoS属性的过程。 The following details how the technical solution of the present invention is a to solve QoS attributes background art HLR and / or the MS QoSR99 properties and QoSR97 / 98 attributes do not comply with the mapping rules protocol results in practical use is larger than the contracted QoS attributes process.

当MS因为位置移动,需要将PDP上下文切换到SGSN2时,采用本发明的技术方案一,SGSN1在发送SGSN Context Response消息前,首先判断该MS的1PDP上下文中的用户签约QoS和/或请求QoS信息中的QoSR99属性和^foSR97/R98属性之间是否满足协议3GPP TS 23.107规定的的映射关系(下述表l),当发现用户签约的QoSR99属性中的上下行Maximum bitrate (最大彼特率)均为64kbps,而QoSR97/98属性中的Peak throughput class为9,不满足表l的映射规则时,则根据表l的映射规则,将QoSR97/98属性中的Peak When the MS because the position, necessary PDP context switch to SGSN2, the technical solution of the present invention a, SGSN1 before sending the SGSN Context Response message, first determines 1PDP context of the MS in the user subscription QoS and / or requested QoS information satisfies mapping relationship (table l) protocol specified in 3GPP TS 23.107 QoSR99 between attributes and ^ foSR97 / R98 attributes when found in the uplink and downlink user subscribed QoSR99 maximum bitrate attribute (Peter maximum rate) were is 64kbps, and QoSR97 / 98 Peak throughput class attributes to 9, the mapping rule is not satisfied in table l, the mapping rules of table l, the Peak QoSR97 / 98 properties

throughput class修改为4;然后将MS请求QoS、签约QoS和最终协商QoS属性中的QoSR97/98部分通过SGSN Context Response消息传送给SGSN2。 4 modified to throughput class; then the MS requests QoS, subscription QoSR97 / 98 portion of the final QoS negotiation and QoS attributes is transferred to the SGSN2 via SGSN Context Response message. 这样, SGSN2通过SGSN Context Response消息接收到的请求QoS和签约QoS中的Peak throughput class变为4,通过这些参数协商的QoS中的Peak throughput class也为4, SGSN2会使用这个协商QoS去更新GGSN。 Thus, SGSN2 QoS request received by the SGSN Context Response message and the QoS contracted Peak throughput class becomes 4, QoS negotiation of these parameters is also Peak throughput class 4, SGSN2 will be used to update the negotiated QoS GGSN.

当MS因为位置移动,又将PDP上下文从SGSN2迁回SGSN1时,SGSN2通过SGSN Context Response消息,将PDP上下文中的请求QoS、签约QoS和最终协商QoS属性(均为QoSR97/98)传送给SGSN1。 When the MS position because, in turn move back a PDP context from SGSN1 SGSN2, SGSN2 via SGSN Context Response message the PDP context QoS request, signing the final negotiated QoS and QoS attributes (both QoSR97 / 98) is transmitted to SGSN1. SGSN1确认MS的网络能力爽持妖99,需要将QoSR97/98属性转换成QoSR99属性,根据下面表2的映射规则,QqSR97/98属性中Peak throughput class参数为4时对应的QoSR97/9g属性中的Maximum bitrate参数为64kbps,因此,转换后的的签约QoS和请求QoS中的Maximum bitrate为64kbps,通过这些参数协商出的QoS中的Maximum bitrate 也是64kbps,然后SGSNl会使用这个协商的QoS去更新GGSN。 SGSN1 confirmed MS network capability cool holding demon 99, needs to be converted QoSR97 / 98 properties to QoSR99 property, according to the table mapping rule below 2, QqSR97 / 98 Properties Peak throughput class parameter QoSR97 / 9g corresponding to the attribute 4 in Maximum bitrate parameter is 64kbps, therefore, contracted QoS and requests Maximum bitrate QoS in after converted to 64kbps, Maximum bitrate negotiated by these parameters QoS is also 64kbps, then SGSNl will use the negotiated QoS to update GGSN. 这样,实际使用的QoS属性就会与签约的QoS属性完全相符。 In this way, QoS attributes actually used will be completely in line with the signing of QoS attributes. <table>table see original document page 19</column></row> <table> <Table> table see original document page 19 </ column> </ row> <table>
